Description
The Heavy Duty U-Bolt Plates provide a robust solution for enhancing the stability and performance of your 1966-77 Bronco. With a thickness of 3/8″, these plates maintain the natural curvature of leaf springs while promoting proper flexing. This design enables pre-loading of the nuts when torqued, which effectively prevents loosening and minimizes axle wrap.
Key features include:
– Zinc plating for improved corrosion resistance
– Inclusion of washers with each set
– Compatibility with a selection of high-strength U-bolts made from 1541 material, engineered to prevent stretching under load
In our February 2021 product update, we added three adjustment holes, allowing for modifications to the wheelbase when paired with our LUBR alignment plates or replacement perches.
